From: Thomas Gleixner <tglx@xxxxxxxxxxxxx> commit 0594729c24d846889408a07057b5cc9e8d931419 upstream. To enable smp_processor_id() and might_sleep() debug checks earlier, it's required to add system states between SYSTEM_BOOTING and SYSTEM_RUNNING. Adjust the system_state check in core_kernel_text() to handle the extra states, i.e. to cover init text up to the point where the system switches to state RUNNING.
